To save money, public banks will not even process a cord blood donation unless they know in advance that they are going to keep it. When the collection first arrives at the lab, it is passed through a cell counting machine. Only collections that have at least 900 million nucleated cells are kept. As a result, over 60%-80% of cord blood donations are discarded. The public bank must absorb the expense of the collection kit and delivery charges for discarded blood; typically $100 per unit.
Most of the diseases on the proven treatment list are inherited genetic diseases. Typically, a child with a genetic disease would require cord blood unit from a sibling or an unrelated donor. Having a sibling cord blood unit can be a great advantage as research shows that treatments using cord blood from a family member are about twice as successful as treatments using cord blood from a non-relative.9a, 17
Stem cells from cord blood can be used for the newborn, their siblings, and potetinally other relatives. Patients with genetic disorders like cystic fibrosis, cannot use their own cord blood and will need stem cells from a sibling’s cord blood. In the case of leukemia or other blood disorders, a child can use either their own cord blood or their sibling’s for treatment.
When all the processing and testing is complete, the cord blood stem cells are frozen in cryogenic nitrogen freezers at -196° C until they are requested for patient therapy. Public banks are required to complete the entire laboratory processing and freeze the cord blood stem cells within 48 hours of collection. This is to insure the highest level of stem cell viability. The accreditation agencies allow family banks a window of 72 hours.
The therapeutic potential of stem cells from the umbilical cord is vast. Cord blood is already being used in the treatment of nearly 80 life-threatening diseases2, and researchers continue to explore it’s potential. Duke University Medical Center is currently using cord blood stem cells in a Phase II clinical trial to see if it benefits kids with Autism. The number of clinical trials using cord tissue stem cells in human patients has increased to approximately 150 since the first clinical trial in 2007. Cord tissue stem cells are also being studied for the potential use in kids with Autism – a Phase I Clinical Trial is underway.
The stored blood can’t always be used, even if the person develops a disease later on, because if the disease was caused by a genetic mutation, it would also be in the stem cells. Current research says the stored blood may only be useful for 15 years.
With the consent of the parents, blood can be collected from the umbilical cord of a newborn baby shortly after birth. This does not hurt the baby or the mother in any way, and it is blood that would otherwise be discarded as biological waste along with the placenta (another rich source of stem cells) after the birth.
Remaining in the umbilical cord and placenta is approx. 40–120 milliliters of cord blood. The healthcare provider will extract the cord blood from the umbilical cord at no risk or harm to the baby or mother.
As the research into umbilical cord blood and it’s therapeutic use for blood diseases has grown, so has the question as to whether people should privately store the cord blood of their offspring for future use. A recent paper on this issue by Mahendra Rao and colleagues advocates the practice of cord blood banking (for treatment of blood diseases) but in the context of public cord blood banks rather than a private cord blood banks. Any adult needing treated would need at least two cord blood samples that are immune compatible. So one sample will not be sufficient. A child might only need one cord blood sample but in the case of childhood leukaemia there is a risk that pre-leukemic cells are present in cord blood sample – and so the child could not use their own cells for therapy.
Brigham and Women’s Hospital and Dana-Farber Cancer Institute jointly oversee the Cord Blood Donation Program to provide hope to all patients in need of a life-saving stem cell transplant. For more information about the stem cell transplant program please visit The Stem Cell/Bone Marrow Transplant Program at Dana-Farber/Brigham and Women’s Cancer Center (DF/BWCC) web site.
“One of the wonderful things about cord blood is that unlike bone marrow, you don’t always need a perfect match in order for it to work,” says Dr. Kurtzberg, who performed the first unrelated cord-blood transplant in the U.S. And it was a public donation that ultimately saved Anthony Dones. Within a week of starting a search, the National Cord Blood Program, a public bank operated by the New York Blood Center, found a “close enough” match. Had the now-3-year-old been forced to rely on a bone-marrow match, he might still be waiting.
Generally not. The reason siblings are more likely to match is because they get half of their HLA markers from each parent. Based on the way parents pass on genes, there is a 25 percent chance that two siblings will be a whole match, a 50 percent chance they will be a half match, and a 25 percent chance that they will not be a match at all. It is very rare for a parent to be a match with their own child, and even more rare for a grandparent to be a match.
Clinical Trials More likely to be used in clinical trials to potentially treat strokes, heart attacks, diabetes, cerebral palsy, autism and a range of other serious medical conditions Less likely to be available to the donor or family members for use in clinical trials More likely to be used in clinical trials for range of other serious medical conditions Less likely to be available for use in clinical trials

To prevent graft-versus-host disease and help ensure engraftment, the stem cells being transfused need to match the cells of the patient completely or to a certain degree (depending on what is being treated). Cord blood taken from a baby’s umbilical cord is always a perfect match for the baby. In addition, immediate family members are more likely to also be a match for the banked cord blood. Siblings have a 25 percent chance of being a perfect match and a 50 percent chance of being a partial match. Parents, who each provide half the markers used in matching, have a 100% chance of being a partial match. Even aunts, uncles, grandparents and other extended family members have a higher probability of being a match and could possibly benefit from the banked cord blood.

* Annual storage fees will be charged automatically to the credit/debit card on file, on or around your baby’s birthday, unless you’ve chosen a prepay option and are subject to change until they are paid.
In order to preserve more types and quantity of umbilical cord stem cells and to maximize possible future health options, Cryo-Cell’s umbilical cord tissue service provides expectant families with the opportunity to cryogenically store their newborn’s umbilical cord tissue cells contained within substantially intact cord tissue. Should umbilical cord tissue cells be considered for potential utilization in a future therapeutic application, further laboratory processing may be necessary. Regarding umbilical cord tissue, all private blood banks’ activities for New York State residents are limited to collection, processing, and long-term storage of umbilical cord tissue stem cells. The possession of a New York State license for such collection, processing and long-term storage does not indicate approval or endorsement of possible future uses or future suitability of these cells.
If you want the blood stored, after the birth, the doctor clamps the umbilical cord in two places, about 10 inches apart, and cuts the cord, separating mother from baby. Then she inserts a needle and collects at least 40 milliliters of blood from the cord. The blood is sealed in a bag and sent to a lab or cord blood bank for testing and storage. The process only takes a few minutes and is painless for mother and baby.
There are over 130 public cord blood banks in 35 countries. They are regulated by Governments and adhere to internationally agreed standards regarding safety, sample quality and ethical issues. In the UK, several NHS facilities within the National Blood Service harvest and store altruistically donated umbilical cord blood. Trained staff, working separately from those providing care to the mother and newborn child, collect the cord blood. The mother may consent to donate the blood for research and/or clinical use and the cord blood bank will make the blood available for use as appropriate.
LifebankUSA seeks mothers in NEW YORK & NEW JERSEY ONLY who will donate both their cord blood and their placenta. The donations support an international registry, clinical trials and research. Donations can be taken from any hospital, but mothers must register at least 8 weeks prior to delivery and pass a health screening.
The umbilical cord blood contains haematopoietic stem cells – similar to those found in the bone marrow – and which can be used to generate red blood cells and cells of the immune system. Cord blood stem cells are currently used to treat a range of blood disorders and immune system conditions such as leukaemia, anaemia and autoimmune diseases. These stem cells are used largely in the treatment of children but have also started being used in adults following chemotherapy treatment.
Umbilical cords have traditionally been viewed as disposable biological by-product. Cord blood, however, is rich in multi-potent hematopoietic stem cells (HSCs). Recent medical advances have indicated that these stem cells found in cord blood can be used to treat the same disorders as the hematopoietic stem cells found in bone marrow and in the bloodstream but without some of the disadvantages of these types of transplants. Cord blood is currently used to treat approximately 70 diseases including leukemias, lymphomas, anemias, and Severe Combined Immunodeficiency (SCID). Six thousand patients worldwide have been treated with cord blood stem cell transplants, although the FDA considers the procedure to be experimental. These multipotent stem cells also show promise for the treatment of a variety of diseases and disorders other than those affecting the blood.
Complications Side Effects As the donor’s stem cells will always be a perfect match, there will be no incidence of graft versus host disease (GVHD), which can be a chronic and even fatal condition. Graft versus host disease (GVHD) is estimated to occur in 60–80 percent of transplants where the donor and recipient are not related. Perfect match! No incidence of graft versus host disease Graft versus host disease (GVHD) occurs in 60%–80% of non-related transplants.
Because the body’s immune system is designed to find and get rid of what it believes to be outside contaminants, stem cells and other cells of the immune system cannot be transfused into just anyone. For stem cell transfusions of any type, the body’s immune system can mistakenly start attacking the patient’s own body. This is known as graft-versus-host disease (GvHD) and is a big problem post-transplant. GvHD can be isolated and minimal, but it can also be acute, chronic and even deadly.
Banking your child’s cord blood really comes down your personal choice. Some people may seem the potential benefits, while others can’t justify the costs. No one debates cord blood cells being a lifesaver, and in recent years, more than 20,000 lives have been saved because of it; however, experts, such as The American Academy of Pediatrics, note that your odds of using this blood is about one in 200,000. Instead of buying into a company’s advertising scheme, be sure to do your own research and deem what’s best for your child’s future.

Current research aims to answer these questions in order to establish whether safe and effective treatments for non-blood diseases could be developed in the future using cord blood. An early clinical trial investigating cord blood treatment of childhood type 1 diabetes was unsuccessful. Other very early stage clinical trials are now exploring the use of cord blood transplants to treat children with brain disorders such as cerebral palsy or traumatic brain injury. However, such trials have not yet shown any positive effects and most scientists believe much more laboratory research is needed to understand how cord blood cells behave and whether they may be useful in these kinds of treatments
